Overview
The ZF 4143.315.024 PLANETARY GEAR is a critical torque-multiplying component engineered for the HL 100 and HL 270 series transmissions. This OEM genuine part sits within the planetary gear set assembly, directly transferring rotational force from the input shaft to the output shaft while managing load distribution across multiple pinions. Designed to withstand high-stress industrial applications, the SKU 4143.315.024 ensures precise gear meshing and minimal backlash. When installed alongside the 4143101009 HOUSING and 4143301025 HOUSING, this planetary gear forms the core of the reduction unit, enabling smooth power delivery in heavy-duty machinery.
Symptoms of Failure
- Whining or grinding noise during gear engagement: Worn planetary gear teeth create audible metallic sounds, especially under load or during deceleration.
- Intermittent transmission slipping: A failing 4143.315.024 gear can cause sudden loss of torque, leading to erratic vehicle movement or inability to hold speed on inclines.
- Metal particles in transmission fluid: Degraded gear surfaces shed debris, contaminating the oil and accelerating wear on adjacent components like the 0634313603 O-RING and 4475280018 SCREW PLUG.
- Overheating in the planetary carrier area: Increased friction from a damaged gear generates excess heat, often detected through fluid discoloration or localized housing hot spots.

Compatibility
This planetary gear is specifically designed for ZF HL 100 and HL 270 series transmissions, commonly found in forklifts, telehandlers, and industrial loaders. It is also compatible with WG180 and WG200 models that share the same planetary carrier architecture. The 4143.315.024 gear interfaces directly with the 0501342341 SUPPORT RING and 4143298457 SEAL KIT to maintain proper alignment and fluid integrity. For optimal performance, always pair this gear with the 0634313591 O-RING and 0636101068 CAP SCREW during rebuilds.
